    The given curve represents the variation of temp-erature as a function of volume for one mole of an ideal gas. Which of the following curves represents the variation of pressure as a function of volume?

    A)                 

    B)  

    C)                              

    D)  

    Correct Answer: A

    Solution :

    From the diagram, \[T=V\,\tan {{45}^{o}}+{{T}_{0}}\] \[\Rightarrow \]               \[T=V+{{T}_{0}}\] For one mole of an ideal gas \[T=\frac{PV}{R}\] Now put it in equation (i), we get \[\frac{PV}{R}=V+{{T}_{0}}\] \[(P-R)\,\upsilon =R{{T}_{0}}\] Hence, graph is rectangular hyperbola.
